Study Notes
Overview of Alcohol
- Ethanol is pure alcohol, colorless, and obtained through fermentation; it acts as an intoxicating agent.
- Blood alcohol concentration (BAC) indicates the amount of alcohol in the blood, expressed in g/100 ml.
Effects of Alcohol
- Alcohol is a central nervous system depressant, affecting heart rate and body temperature.
- Peak blood concentration of alcohol typically occurs within 1 hour of consumption.
Absorption and Metabolism
- Alcohol absorption begins in the stomach and continues in the small intestine, eventually metabolized predominantly in the liver.
- Measurement of alcohol levels can be done through breathalyzers, urine samples, and blood tests, with a legal driving BAC limit of 0.08% in Canada.
Immediate Effects Based on BAC
- BAC of 0.02-0.03: Slight euphoria and relaxation; no loss of coordination.
- BAC of 0.04-0.06: Impaired reasoning, memory, and driving skills; decreased caution.
- BAC of 0.08-0.09: Significant impairment of judgment and motor skills; illegal to drive.
- BAC of 0.10+: Severe impairment of coordination, judgment, and control; risk of unconsciousness at 0.30.
Alcohol Consumption Statistics in Canada
- Approximately 22 million Canadians (15+) reported alcohol use in the past year.
- Men tend to consume more and engage in riskier drinking behaviors than women.
Heavy and Binge Drinking Definitions
- Heavy Drinking: 5 or more drinks for men, 4 or more for women on one occasion, at least once a month.
- Binge Drinking: 5 or more drinks for men, 4 or more for women in about two hours.
Short and Long-term Effects
- Short-term effects include intoxication, accidents, injuries, and violent behavior.
- Long-term effects raise the risk of liver diseases (hepatitis, cirrhosis) and various cancers but may lower cardiovascular disease risks by raising HDL cholesterol levels.
Pregnancy and Alcohol
- No safe amount of alcohol during pregnancy; risks include miscarriage and Fetal Alcohol Spectrum Disorder (FASD), which can lead to lifelong disabilities.
Alcohol-Related Problems
- Alcohol abuse: Continued use despite physical, social, or occupational issues; diagnosed based on a range of negative consequences.
- Alcohol dependence: Craving for alcohol with tolerance, withdrawal symptoms, and unsuccessful attempts to reduce intake.
Alcoholism
- A chronic and progressive disease marked by a loss of control over drinking, preoccupation with alcohol, and distorted thinking patterns.
Treatment Options
- Detoxification: Medically supervised withdrawal process lasting 7-21 days.
- Inpatient treatment: Programs typically lasting 30-90 days with counseling.
- Behavioral therapies focus on coping skills and self-monitoring, while harm reduction programs manage the negative impact of alcohol.
Best Practices for Reducing Alcohol-Related Harm
- Minimum legal drinking age enforcement and restrictions on selling hours.
- Public monopolies on alcohol to control distribution and density.
- Implementation of alcohol taxes, sobriety checkpoints, and lower BAC limits to enhance public safety.
